70-03A is a high quality adhesive and sealant based on Silyl Modified Polymer (SMP). 70-03A is designed for making elastic construction joints that require high strength.
FEATURES
Solvent, isocyanate, and pvc-free
High green strength and with very good workability
Good adhesion on many substrates without the use of a primer
Permanently elastic within temperatures from -40°F to 212°F (-40°C to 100°C)
Neutral, odorless and fast curing
Paint compatible with most industrial paint or lacquer systems, both alkyd resin and dispersion based (due to the large scale of different types of industrial paints a paint compatibility test is recommended)
Paintable after skin forming (wet-on-wet); this will not influence the cure rate
Note: Due to the large scale of different types of industrial paints, a paint compatibility test is recommended. Paintable after skin forming (wet-on-wet); this will not change the cure rate of the bead.
